GVP Compo + EGS 110/24
[ continuation ]
[ 1600×1280 would look pretty nifty on a 19" monitor! ]
NOTE: all above resolutions can be in any color depth up to 24 bit.
Special applications (256 colors max, limied only by VRAM memory size):
3200×2560 [ this is an astonishing 168 DPI on a 19" monitor, enough to make
any sourpuss happy 🙂 ]
SPECIFICATION OVERVIEW
bus interface: Directly connects to high-speed 32-bit wide
local bus of GVP's COMBO accelerator boards
for the A2000.
Internal graphics architecture: 64-bit interleaved
Framebuffer: 4MB or 8MB of high-speed VRAM with 25ns
serial access time. Directly mapped into
030/040 host CPU. VRAM is fully expandable
from 4MB to 8MB using GVP's special
SIMMVR-1MB-80 SIMM modules.
Graphics memory architecture: 32-bits chunky
Random VRAM access: 80ns-normal or 40ns in pagemode
Video port access: 12.5ns [smokin']
Maximum pixel display speed:
110 million pixels per second in full
24-bit color depth per pixel. [ compared
to VGA resolution which has 768K total
pixels ]
Display resolution: Fully programmable in steps of 4 pixels per
scan line.
Display Refresh Rate: Fully programmable up to 140Hz [ little,
teeny-tiny, itty-bitty pixels – and more
than a megapixel 🙂 ]
Display Scan Rate: Fully programmable up to 80KHz.
CPU Bus bandwidth: 50MBytes per second (without using 68040
burst mode, higher when using burst mode of
68040).
Graphics data bus bandwidth:
up to 440MBytes/sec with 65-bit interleave.
Max blockwrite data bandwidth:
up to 576MBytes/second
Average Line Draw rate: 3 million pixels per second with 68040.
Hardware sprite/cursor support:
64×64 pixels built-in hardware cursor
Pseudo color modes: 2 colors out of 16M, 4 out of 16M, 16 out
of 16M, 256 out of 16M.
True color modes: 65536 colors (16-bits per pixel) or
